Description

Technical Field

[0001] This utility model relates to the technical field of rail transit interior decoration, and in particular to a detachable integrated roof structure. Background Technology

[0002] In the field of rail transit interior assembly, the integrated roof structure, as an important component of the interior decoration and functionality of the carriage, has a significant impact on the aesthetics, functionality, and subsequent maintenance of the vehicle's interior environment through its design and construction methods. Traditional integrated roof structures, after installation, often only allow for the removal of the grille for cleaning and maintenance of the air ducts; other parts such as the roof panel, air ducts, and crossbeams are difficult to disassemble, causing considerable inconvenience for maintenance work.

[0003] Currently, the integrated top-mounted structure design on the market is relatively fixed and lacks flexibility. Especially when it is necessary to thoroughly clean the air duct or replace internal consumable parts (such as rubber strips), due to structural limitations, large-scale disassembly must be carried out, which may even affect other components that are assembled with the top-mounted structure. This not only increases maintenance costs but also extends the maintenance cycle. Utility Model Content

[0004] The purpose of this utility model is to provide a detachable integrated roof structure to address the shortcomings of existing technologies. This structure allows for the complete disassembly of components such as the grille, roof panel, crossbeams, and air ducts. Furthermore, the internal air ducts can be cleaned without disassembling the longitudinal beams, and consumable parts such as internal rubber strips can be easily replaced. The entire process does not affect other components that are assembled with the roof, such as handrails and lighting fixtures. This further improves the convenience of internal maintenance in rail transit vehicles, reduces maintenance time and costs, and increases vehicle operating efficiency. Simultaneously, by simplifying maintenance procedures and reducing the impact on other components, it further enhances the stability and durability of the vehicle's interior.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a detachable integrated roof structure, comprising a roof module and longitudinal beams; two longitudinal beams are disposed on both sides of the roof module, and the roof module is mounted on the vehicle body via the longitudinal beams; the roof module includes a grille, a roof plate, a crossbeam, and an air duct; the grille is detachably disposed between the crossbeam and the longitudinal beam; the crossbeam is detachably connected and fixed to the longitudinal beam, and the roof plate is detachably connected and fixed to the crossbeam; the air duct is detachably connected and fixed to the longitudinal beam and the roof plate.

[0006] Furthermore, one side of the grille is detachably mounted on the crossbeam via a grille removal point, and the other side of the grille is fixedly hung on the longitudinal beam.

[0007] Furthermore, the grille is detachably mounted on the crossbeam via bolts at the grille removal point.

[0008] Furthermore, the crossbeam is detachably connected and fixed to the longitudinal beam via a crossbeam disassembly point.

[0009] Furthermore, the crossbeam is detachably connected and fixed to the longitudinal beam via bolts at the crossbeam disassembly point.

[0010] Furthermore, the top plate is detachably connected and fixed to the crossbeam via a top plate disassembly point.

[0011] Furthermore, the top plate is detachably connected and fixed to the crossbeam by bolts at the top plate disassembly point.

[0012] Furthermore, the air duct is detachably connected and fixed to the longitudinal beam and the middle top plate through the first air duct disassembly point and the second air duct disassembly point, respectively.

[0013] Furthermore, the air duct is detachably connected and fixed to the longitudinal beam and the central top plate via bolts at the first air duct disassembly point and the second air duct disassembly point, respectively.

[0014] Furthermore, the cleaning, maintenance, or replacement of parts involves disassembling the central top module in the order of the grille, the central top plate, the crossbeam, and the air duct.

[0015] The system comprises a central roof module and longitudinal beams; two longitudinal beams are positioned on either side of the central roof module, which is then mounted on the vehicle body via the longitudinal beams; the central roof module includes a grille, a central roof plate, crossbeams, and air ducts; the grille is detachably disposed between the crossbeams and the longitudinal beams; the crossbeams are detachably connected and fixed to the longitudinal beams; the central roof plate is detachably connected and fixed to the crossbeams; and the air ducts are detachably connected and fixed to the longitudinal beams and the central roof plate. This structure achieves complete detachability of components such as the grille, central roof plate, crossbeams, and air ducts. Furthermore, the internal air ducts of the central roof can be cleaned without disassembling the longitudinal beams, and consumable parts such as internal rubber strips are easily replaced. The entire process does not affect other components related to the central roof, such as handrails and lighting fixtures. This further enhances the convenience of internal maintenance in rail transit vehicles, reduces maintenance time and costs, and improves vehicle operating efficiency. Simultaneously, by simplifying maintenance procedures and reducing the impact on other components, it further enhances the stability and durability of the vehicle's interior.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] In the description of this utility model, it should be noted that the orientation or positional relationship indicated by terms such as "center", "up", "down", "left", "right", "vertical", "horizontal", "inner", and "outer" are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] A detachable integrated top structure, such as Figure 1 , 2As shown, it includes a central roof module 1 and longitudinal beams 2; two longitudinal beams 2 are arranged on both sides of the central roof module 1, and the central roof module 1 is mounted on the vehicle body through the longitudinal beams 2; the central roof module 1 includes a grille 3, a central roof plate 4, a crossbeam 5, and an air duct 6; the grille 3 is detachably arranged between the crossbeam 5 and the longitudinal beams 2; the crossbeam 5 is detachably connected and fixed to the longitudinal beams 2, and the central roof plate 4 is detachably connected and fixed to the crossbeam 5; the air duct 6 is detachably connected and fixed to the longitudinal beams 2 and the central roof plate 4.

[0026] Specifically, the modular installation of the central roof structure is achieved through the combined design of the central roof module 1 and the longitudinal beam 2, facilitating overall disassembly and reinstallation, improving maintenance efficiency. Unlike traditional structures, it does not require large-scale disassembly; only the parts requiring maintenance need to be disassembled and reassembled in a modular manner, reducing the impact on other components and lowering maintenance costs and time. The grille 3 is designed to be detachable, making the cleaning and maintenance of the air duct more convenient. The grille 3 can be easily removed for thorough cleaning of the air duct without disassembling the entire central roof structure, improving maintenance flexibility and convenience. The central roof plate 4 and the crossbeam 5 are both designed to be detachably connected, increasing the structural flexibility. When maintenance is required on components on the air duct or crossbeam 5, the central roof plate 4 or crossbeam 5 can be removed individually, avoiding damage to the entire central roof structure and reducing maintenance difficulty and costs. The structural design considers cleaning the inside of the air duct after installation. By disassembling the grille, tools can be used to clean the internal air duct, thoroughly cleaning it or replacing damaged components such as rubber strips, improving the service life and performance of the air duct.

[0027] As a preferred embodiment of the above, such as Figure 1 , 2 As shown, one side of the grille 3 is detachably mounted on the crossbeam 5 via grille removal point 3-1, and the other side of the grille 3 is fixedly hung on the longitudinal beam 2.

[0028] As a preferred embodiment of the above, such as Figure 1 As shown, the grille 3 is detachably mounted on the crossbeam 5 via bolts at the grille removal point 3-1.

[0029] Specifically, by setting up a grille removal point 3-1 with bolts, the grille 3 can be more easily removed from the crossbeam 5 without having to disassemble the entire top module or crossbeam as in traditional designs. The other side of the grille 3 is fixed on the longitudinal beam 2, which not only ensures the stability of the grille but also makes the grille more flexible in disassembly and installation. This allows maintenance personnel to disassemble the grille more quickly to clean or maintain the air duct and then reinstall the grille, thus greatly optimizing the maintenance process.

[0030] As a preferred embodiment of the above, such as Figure 1 , 2 As shown, the crossbeam 5 is detachably connected and fixed to the longitudinal beam 2 via the crossbeam disassembly point 5-1.

[0031] As a preferred embodiment of the above, such as Figure 1 , 2 As shown, the crossbeam 5 is detachably connected and fixed to the longitudinal beam 2 by bolts on the crossbeam disassembly point 5-1.

[0032] Specifically, by setting a disassembly point 5-1 on the crossbeam 5 and using bolts for detachable connection, the modular design of the central roof structure is enhanced. This allows the crossbeam 5 to be disassembled and replaced as an independent module, improving the structure's flexibility and maintainability. It also makes the connection between the crossbeam 5 and the longitudinal beam 2 more robust and easier to disassemble. Maintenance personnel can easily disassemble the crossbeam 5 simply by loosening the bolts, greatly simplifying the disassembly and installation process.

[0033] As a preferred embodiment of the above, such as Figure 1 , 2 As shown, the top plate 4 is detachably connected and fixed to the crossbeam 5 via the top plate disassembly point 4-1.

[0034] As a preferred embodiment of the above, such as Figure 1 , 2 As shown, the top plate 4 is detachably connected and fixed to the crossbeam 5 by bolts at the top plate disassembly point 4-1.

[0035] Specifically, by setting a disassembly point 4-1 for the central roof panel and connecting it with bolts, the central roof panel 4 can be disassembled and replaced as an independent module. This greatly enhances the maintainability of the central roof structure, allowing maintenance personnel to more easily inspect, clean, or replace the central roof panel, making the connection between the central roof panel 4 and the crossbeam 5 both secure and easy to disassemble. Maintenance personnel can easily disassemble the central roof panel 4 simply by loosening the bolts, without the need for large-scale disassembly of the entire central roof structure, thus improving the flexibility of disassembly and installation.

[0036] As a preferred embodiment of the above, such as Figure 1 , 2 As shown, the air duct 6 is detachably connected and fixed to the longitudinal beam 2 and the middle top plate 4 via the first air duct disassembly point 6-1 and the second air duct disassembly point 6-2, respectively.

[0037] As a preferred embodiment of the above, such as Figure 1 , 2 As shown, the air duct 6 is detachably connected and fixed to the longitudinal beam 2 and the middle top plate 4 by bolts on the first air duct disassembly point 6-1 and the second air duct disassembly point 6-2, respectively.

[0038] Specifically, by setting up a first air duct disassembly point 6-1 and a second air duct disassembly point 6-2, and connecting them with bolts, air duct 6 can be disassembled and replaced as an independent module. This enhances the convenience of air duct maintenance, allowing maintenance personnel to more easily clean the interior of the air duct, replace consumable parts, or perform other maintenance work. It ensures that the connection between air duct 6 and the longitudinal beam 2 and the central top plate 4 is both firm and precise. Bolted connections provide stable mechanical properties, ensuring the stability and safety of air duct 6 in the connected state. Traditional air duct maintenance often requires large-scale disassembly of the entire central top structure, which not only increases maintenance difficulty but may also introduce additional risks. However, through the design of the air duct disassembly points, maintenance personnel can perform air duct maintenance work more safely and conveniently, reducing maintenance difficulty and risks. The process of disassembling and reinstalling air duct 6 is simpler and faster, significantly shortening maintenance time and improving maintenance efficiency. At the same time, because air duct 6 can be disassembled and replaced as an independent module, maintenance personnel can focus more on the maintenance of the air duct itself, thereby improving maintenance quality.

[0039] As a preferred embodiment of the above, such as Figure 1 As shown, the cleaning, maintenance, or replacement of parts involves disassembling the central top module 1 in the order of the grille 3, the central top plate 4, the crossbeam 5, and the air duct 6.

[0040] Specifically, by disassembling in the order of grille 3, top plate 4, crossbeam 5, and air duct 6, each step has a clear objective and sequence, avoiding confusion or omissions during disassembly. This orderly disassembly method greatly improves work efficiency and shortens maintenance time. Through sequential disassembly, maintenance personnel can more clearly see the various components inside the top plate module, facilitating inspection and evaluation. If parts need to be replaced, they can be installed in reverse order of disassembly, ensuring that each component is correctly placed. Sequential disassembly helps reduce unnecessary damage and waste, lowering maintenance costs. Simultaneously, the more orderly and efficient disassembly process also reduces the time and labor costs required for maintenance.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
